 Purpose      : This file is part of a point-of-sale software package
                originally written for Table-Service Restaurants.
              
 Date         : July 8th of 2012
              
 History      : The application that this software file belongs to was 
                written over a 3-Year period.  The first version was written
                in C# .Net 3.5 using Windows Forms.  Being new to .Net at
                the time, I soon learned of Windows Presentation Foundation,
                liked the graphics capabilities and databinding so I
                migrated to WPF.  When the .Net 4.0 framework was released
                the application was migrated from 3.5 to 4.0. Now today,
                .Net 4.5 RC is out and I was already in process of migrating
                before I made this public.
                
Excuse Me     : Please excuse the coding style, it is not representative of
                my typical work.  During the three years I was under a very
                tight budget, constantly running out of funding and was 
                working 18 hour days hyped up on 5-Hour Energy.  The 
                design is not textbook.  It is monolythic because of
                previous issues I will not get into.  There are few comments
                in the code and the ones that are there may be incorrect.
                
What it is not: This is not the exact version that I took through PA-DSS 2.0
                nor is it the exact version running at my customer sites.
                I removed some details for security purposes including some
                encryption algorithms.  The reporting was removed because
                I was including a third party library that cannot be 
                published with this Open Source.
                
What it is    : This application has been running at high volume restaraunts
                for over a year.  It never freezes, crashes or does anything
                unexpected.  So long as it is built, installed and configured
                correctly, it is a strong system that we can all enhance.
